I received a "suggestion" from one of my "followers" about our current inability to download high-quality PNG Image(s) of various sizes for the generated logo (or "Default Avatar").

For example, I had a difficult time trying to re-size my "Identicon (Generated)" logo (which I saved/downloaded from the "[blog address here\.wordpress.com/wp-admin/options-discussion.php" webpage) and lost the quality of this PNG image because of pixilation.

Would we (soon) be able to download the generated logo of various sizes for areas such as "Gravatars/Wallpapers/Blog backgrounds/Header Images/et cetera"?

I do not know whether I understand correctly what you mean, but if you want to download the gravatar-images (like the red icon you are using on this forum) in full size, just copy the images url and remove the parameter.
